Trust Wallet Adds Gas Sponsorship on Ethereum to Allow Zero Balance Swaps

Trust Wallet has introduced gas sponsorship for token swaps on Ethereum, allowing users to complete swaps even when their wallet holds no ETH for gas fees. The wallet detects low balances automatically and covers the gas cost, up to four swaps per day. This directly solves one of the most common causes of failed transactions in crypto wallets and marks a practical change in how self custody wallets handle network fees.

What Problem Does Gas Sponsorship Solve in Crypto Wallets?

Gas fees are the base cost required to perform any action on a blockchain. On Ethereum, this fee is paid in ETH, regardless of which token is being moved or swapped. This design has long caused friction for users.

A common scenario looks like this. A user holds stablecoins or ERC-20 tokens, wants to swap them, but has zero ETH left. The transaction fails, even though the wallet has enough value to cover the swap itself.

This issue affects both new users and experienced traders. It leads to:

• Failed swaps
• Extra steps to buy or bridge small amounts of ETH
• Confusion for users who already have funds but cannot move them

Trust Wallet’s gas sponsorship feature addresses this directly by paying the gas fee when the wallet detects that the native balance is too low.

How Does Trust Wallet Gas Sponsorship Work?

Gas sponsorship is built directly into the Trust Wallet app. Users do not need to enable a setting or apply for access.

When a user initiates a swap, Trust Wallet checks the wallet’s native token balance. If there is not enough ETH to cover gas on Ethereum, the wallet automatically sponsors the transaction fee.

The process happens in real time and does not add extra steps to the user flow. The user signs the transaction as usual, and the swap completes without requiring ETH in the wallet.

Trust Wallet describes the system as automatic and interruption free. 

Worth noting, users still maintain full control of their private keys and assets. Trust Wallet does not take custody of funds or execute swaps without user approval. The wallet simply covers the gas fee while the transaction is signed and authorized by the user’s own wallet.

Which Blockchains Support Gas Sponsored Swaps?

Trust Wallet has launched gas sponsorship across three major networks. Each chain has slightly different rules.

The supported chains are:

• Ethereum
  Up to four gas sponsored swaps per day
  Minimum swap size of $50 
• BNB Chain
  Up to four gas sponsored swaps per day
  No minimum swap amount
• Solana
  Up to four gas sponsored swaps per day
  Minimum swap size of around $200

The feature currently supports swaps only. Trust Wallet has confirmed that support for token transfers, such as sending assets to another wallet, is planned next.

Why Zero Gas Swaps Matter on Ethereum Specifically

Ethereum remains the most widely used smart contract network, but it is also known for higher gas costs and frequent failed transactions during network congestion.

For Ethereum users, gas sponsorship changes several practical pain points.

First, it reduces failed transactions caused by empty ETH balances. Second, it removes the need to keep small amounts of ETH idle just for gas. Third, it simplifies the experience for users who mainly hold stablecoins or DeFi tokens.

This is especially relevant for users interacting with decentralized exchanges, NFT platforms, and DeFi protocols, where frequent swaps are common.

Trust Wallet’s Trust Alpha Product

Gas sponsorship is not an isolated update. It fits into a wider push by Trust Wallet to simplify onchain activity while keeping self custody intact.

Last October, Trust Wallet launched Trust Alpha, an in app platform that gives users access to early stage Web3 projects and rewards.

Trust Alpha is built directly inside the Trust Wallet app and uses the Trust Wallet Token, or TWT, as its access and reward mechanism.

What is Trust Alpha and how does it work?

Trust Alpha is a wallet native launch and growth platform. Users do not need to connect to external sites or third party apps.

The platform allows users to:

• Explore early stage crypto and Web3 projects
• Join reward pools directly in app
• Earn and claim rewards without leaving Trust Wallet

For builders, Trust Alpha provides access to millions of active wallet users without separate integrations.

The system revolves around TWT. Users who hold or use TWT can unlock access to reward pools, airdrops, and campaigns.

Conclusion

Trust Wallet’s gas sponsorship feature allows users to swap tokens on Ethereum, BNB Chain, and Solana even with zero native token balance. By covering gas fees automatically, the wallet reduces failed transactions and removes a common source of friction. 

The feature works within a self custody model and is limited to a fixed number of swaps per day. Alongside Trust Alpha, it reflects a broader focus on simplifying onchain activity without changing blockchain rules or custody structures.
